SQLite table preview in Quick Look is something I didn't know I needed. I constantly open DB Browser just to check a quick schema. Does it handle large databases or is there a file size limit where it becomes impractical?

@greythegyutae Give it a shot! There's a file size cap right now to keep previews snappy, but I'm looking into handling larger files down the road.

📌

Hey everyone! I'm the developer behind Looq. I built Looq because Quick Look on macOS handles images and PDFs great, but falls flat for everything else developers touch daily. Press Space on a Markdown file, a .swift file, or a SQLite database — you get raw text or a blank panel. I kept opening full editors just to glance at a file, and it added up. Looq is a single Quick Look extension that previews: Markdown — full GFM, KaTeX math, Mermaid diagrams, GitHub Alerts, auto TOC Source code — syntax highlighting for 190+ languages, auto-formatting for minified JSON/CSS/XML Data files — CSV and SQLite as native sortable tables with column headers and type info Archives — browse ZIP/TAR contents without extracting Diff/Patch — color-coded with dual line numbers Everything runs locally on your Mac. No analytics, no telemetry, no accounts. What file types or features would you want to see next?

The Mermaid diagram preview sold me instantly. I write a lot of docs in Markdown and always have to open a separate editor just to check if the diagrams render correctly. Does it support live-reloading, like if I edit and save a file while Quick Look is open?

@ray_artlas Thanks! Right now you'd need to press Space again after saving to refresh the preview. Live rendering is on the roadmap — it's a great use case for Mermaid workflows and I want to get it right.

@parcse Good to know, thanks! Looking forward to live rendering. Mermaid diagrams change a lot while writing so that would save a lot of Space-pressing.

@ray_artlas Yeah, that's exactly the kind of workflow it'll help with. Stay tuned!

Nice idea !! extending Quick Look for dev files makes a lot of sense. @parcse

Would be cool to see support for log files or very large files too : is that something you're planning to add?

@amraniyasser Appreciate it! I'll have to see how practical it is to pull off, but definitely something I'll keep in mind.

Looq 1.2: Live Rendering for Quick Look previews

Looq 1.2 adds Live Rendering. Edit a Markdown file, hit save, and the Quick Look preview updates on its own. No closing and reopening.

The key part: it doesn't flash. Code blocks keep their highlighting, Mermaid diagrams stay put, and only the parts you changed get re-rendered. Old content stays on screen until the new version is ready, then swaps in one frame.
